I didn't take that as "gibberish" I interpreted that as "I don't know" as in maybe he doesn't speak the language and had someone else do the lyrics while he just made it sound amazing. If he specifically said they just made it up, then sure I would accept that. At the very least they probably have a voice track that they could transliterate so it wouldn't be a mystery what is being said, even if it is a fictional language or gibberish, as even gibberish can be spelled out in real words.
